CHILL.

SPECIFICATION forming part of Letters Patent No. 533,634, dated February5, 1895.

Application filed June 19,1894. Serial No. 515,041. (No model.)

To ctZZ whom it may concern:

Be it known that I, ABRAHAM CORBETT, a citizen of the United States,residing at Hagerstown, in the county of Washington and State ofMaryland, have invented certain new and useful Improvements in Chills;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in chills,and is designed particularly for use in the operation of casting asuitable base on and about the lower end of a fence post. It isdesirable in apparatus of this general character that means should beprovided for properly guiding the chill so that it may seat itself uponthe flask in exact position above the casting cavity therein, withoutrequiring any supplemental adjustment or any defective result or loss oftime incident thereto. It is furthermore desirable that the chill shouldbe provided with means for quickly and effectually centering the postand holding it rigidly in place during the casting operation, butreadily detachable as soon as the casting has been completed. Myinvention comprises an apparatus realizing these requirements, andpermitting a great number of posts to be provided with bases castthereon, at a small expense, and with the employment of comparativelyunskilled labor.

In the accompanying drawings, Figure 1 represents a top plan view of oneform of chill embodying my invention, and showing a fence post securedtherein prior to casting. Fig. 2 represents a central vertical sectionthereof, the chill being shown in position upon the flask. Fig. 3represents a top plan view of the guide for centering the chill upon theflask. Fig. 4 represents a top plan view of a modified form of chill.Fig. 5 represents a front elevation of one of the separable partsthereof; and Fig. 6 represents in vertical section a chill of the kindshown in Figs. 1 and 2 but having a different means for securing thepost in place. Figs. 7 and 8 represent respectively a sectional view anda plan view of a further means for securing the post in place within thechill.

Similar letters of reference indicate similar parts throughout thevarious views.

Referring to the form of the invention shown in Figs. 1 to 3, Aindicates the main body portion of the chill, which is, as usual, madeof metal and has a pouring hole or gate a and a chill recess b. Thismain body portion is provided with a collar 0, integral with it, whichcollar is bored centrally at (1 so as to have an inner diameter somewhatin excess of the fence posts to be inserted therethrough, one of whichisindicated ate. The

purpose of this collar is to serve as a means for guiding the fence postwithin the chill and to permit it to be securely but removably clampedin exact alignment with the center of the chill recess 1). The preferredclamping means for this purpose consists of the set screws f of anysuitable number, said set screws passing through appropriate openings inthe collar and being adapted by means of a Wrench to clamp the fencepost in place as indicated in the drawings. Instead of the set screwsf,however, I may employ, if desired, two tapering keys f (see Fig.Gfiadapted to be driven at right angles to each other, through openingsin the collar, and through openings in the fence post as will be readilyunderstood.

In the form of chill shown in Figs. 4 and 5, the same general featuresof construction are present as indicated by the reference letters. Thechill is made up, however, in this case of two parts, A, A adapted to beheld together by connecting bolts n, and to be separated by removing thenuts m of said bolts. This separable chill may be employed when, for anyreason, it is desirable after the casting operation to remove the chillfrom the fence post without slipping it up along and off the end offence; but, for most purposes, I prefer the construction shown in Figs.1 and 2.

In order to center the chill in proper position upon the flask I placein a suitable recess in the flask as indicated in Fig. 2 an intermediateplate B Whose central aperture is located directly above the castingcavity o, and which is provided with a rim or ridge to theinner wall ofthe collar.

within which the chill is adapted to fit. By this expedient the chillwill always be seated with accuracy at exactly the desired place withrelation to the flask, and each fence post therefore will be united withits base at exactly the same point, so that the uniformity of the workdone with the chill and flask can be absolutely relied upon.

The operation of the invention as a whole will be apparent to thoseskilled in the art. The mold cavity for the fence base is first made inthe flask in the usual manner. The plate B is then put in place, and thechill,

within which the fence post has just been clamped, is placed upon theplate. The molten metal is then poured through the pouring opening andfills the mold cavity and chill recess thereby being cast upon the lowerend of the post. After the castingoperation the chill can be removed byloosening the set screws or knocking out the keys, as the case may be.

The construction shown in Figs. 7 and 8 illustrates a further means forremovably holding or clamping the fence post within the chill, saidmeans consisting of wedges f preferably conforming to the circularperiphery of the post and guided within recesses in It will, of course,be understood that these wedges may be tightened upon the fence post bya slight blow of a mallet or the like sufficiently to hold the postsfirmly during the casting operation, and after the completion of thecast may be withdrawn in any suitable manner.

By the expression integral with the chill as employed in the claims, Iintend to cover broadly any construction wherein the collar forms aunited structure with the main body portion of the chill, whether bybeing cast in one piece or otherwise united therewith. It will beunderstood that this is an essential feature of the device, as itenables the fence post to be clamped to the chill and held positively infixed relationship thereto during the casting operation,therebydispensing with the employment of an outside frame, as heretoforeprovided, for maintaining the post in a vertical position and forpreventing it from rising during pouring.

Having thus described the invention, what I claim is- 1. A chill forflasks employed for casting bases to fence posts, said chill beingprovided with a chill recess above and communicating.

with the mold cavity of the flask, a collar integral with the chill, andhaving a perforation extending upwardly from the chill recess wherebythe fence post may enter the chill recess, and releasable devices forclamping the fence posts directly to the collar whereby the fence-postmay be clamped in fixed connection to the chill during the castingoperation; substantially as described.

2. A chill for flasks employed for casting bases to fence posts, saidchill being provided with a chill recessabove and communicating with themold cavity of the flask, a collar integral with the chill, and having aperforation extending upwardly from the chill recess whereby the fenceposts may enter the chill recess, and releasable devices for clampingthe fence posts directly to the collar, said devices passing through thewalls of the collar; substantially as described.

3. A chill for flasks employed for casting bases to fence posts, saidchill being provided with a chill recess above and communicating withthe mold cavity of the flask, a collar integral with the chill andhaving a perforation extending upwardly from the chill recess, wherebythe fence posts may enter the chill recess, and adapted to bear upon theouter surface of the post; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
